Application :tiled January 20, 1928. Serial No. 243,156.

My invention re ates to buildings and particularly to novel means for r'znningv wall openings therein.

@ne et the principal objects et my invention is to provide a rigid and unyieldinpn iralne particularly for a door opening, together with means readily adaptinn,l the traine to receive a wood jamb and molding'.

A further particular object is to provide means in connection with snch av frame adapting it to be manufactur-ed, handled and shipped in a lnoclied down condition and to be assembled on the job 'without the use ot special metal working;q equipment. The desired result is secured by so arranging the parts that the wood bloelrs carried by the iframe and adapted to receive the wood trim serve also as means for receiving' nails or screws projected through overlapping 1netallic portions et the trame. This means together with the interlocking relation of: the metallic parte assures a rigid and unyielding :traine adapted to support the tile or other wall elements and to receive the wood trim, that is desired in many cases.

The result ot such construction is that the wall may be completed with the assurance that there will be no cracks in the plaster at the junction ol the traine with the wall, due to shrinkage., warping, or distortion oit a wood buck, yet permittingl the use oi the desired wood trim without special `fastening` devices therefor.

flhe invention will be more readily understood by roter-ring to the accompanying drawings, in which Fig'. 1 is a fragmentary elevation of the end et a door frame constructed in accordance with my invention; j'

llig. 2 is an enlarged perspective view ot a corner thereof;

Fig. 3 is a perspective lView of one et the fastening; plates;

Fig. et is a plan view et one end oil' traine and Fig. 5 is a sectional View through a cornpleted wall constructed in accordance with my invention. I

ln the drawings it will be seenthat the frame elements indicated generally by the letters A, B, and C are olf generally channel shape, the channels comprising a web 10, flanges 1l., and :margins 12 ane* d' posed relative to the Y the ingplaster terminals. The tree edge 13 of the margins is rebent to `term an undercut portion or plaster hey and to serve another jan-pose later described. @ne or both sides olf the channel nicinhers may be constructed as described.

ln order to provide simple means of connection l etween adjacent angularly disposed traine elements, l provide l.. shaped plates as shown in 8, the leg le ot which plates is secijlred by welding or otherwise to a 'llangge 1l ot the channel A, while the leg 15 lies alone'side oil or immediately adjacent to the corresponding, flange 11 of the adjacent cl rnnel ll. Extending along the inner edge et the leg 15 is a lip 16 bent out from the metal` et the les; and adapted to enter and interlock with the space between the undercut portion 13 and thev flange el. the channel. it will he noted that the angular plates are oil2 conside )ably greater depth than the depth ot the channels and in order to stiilien and unite the plates on opposite sides oit the channels and to define the space to be occupied by wall tile, l provide short ll shaped members 17, 18. The member 17 is welded, as indicated, to the top channel and to the legs 141- ot the plates, while the member 18 is welded at its sides only to the legs 1li olt the plates.

lhe parts as described are constructed in the shop and shipped in knocked down condition. ll'n. assembling', the worlnnan merely engages the ends sliding;- the parts into cooperating and interlocking relation. He will then seat a wood block, such as indicated at 19 in. dotted lines in liigrs. 1 and 2, and drive nails or screws through the overlapping; adjacent portions ol the leg 15 oil the platea and the tlange et the vertical channel and into the wood bloclr. The block serves as a secure holding means for the nails and assures a jjiermanent uniting et the traine elements without possibility olE deterioration. lli desired, registieringl holes 20 may be provided in the shop,-the holes heingr; formed s htly smaller than the size oit the nails or screws to be used. This is not absolutely essential, however, as due to the relatively thin character of metal employed in the channels, nails may he driven through the t sses without great dillienlty.

A the channel members are j yid in their CII .fill

struck out ears`2l which are positioned to hold the Wall tile and the frame in rigid relation.

At intervals'in the length of the channel frame members I seat wood blocks one of which Vis indicated at 22 in Fig. 5 which' may, if desired, be held in place by nails 23 extending through the flanges of the channel. These spaced blocks serve as means of attachment for a Wood jamb 24 and molding 25.

In order to suitably stiffen the channels, I may,V prefer to provide corregations 26 at intervals therein as shown in Fig.` 1.

WVhile I have shown the interlocking corner clips in a certain relation, it isv obvious that changes may be made in this relation and in the general design as to other Jfeatures Without losing many of the Yadvantages of j the invention disclosed. Therefore, Idonot Wish to be-limited except as indicated' in the appended claims.

L Iclaimv: Y 1. A1 frame element for wall openings comprising in combination a plurality of metallic channel, shaped elements having attheir junction angles, said overlapping. portions having registering. apertures, a Wood block within a channel shaped elementsfand vfastening devices extending lthrough the apertures and into the Wood block.

2. A frame element for Wally openings comprising in combination aplurality of metallic channel Vshaped elements having overlapping portions at their junction angles, said loverlapping portions having. registering apertures, a Wood block. Within ya channel shaped element, fasteningl devices extending lthrough the apertures and into the Wood block, and trim for the opening secured to saidy Wood block.

3. In. means-for framing Wallr openings, the combination of a plurality of metallic channels having. overlapping portions at their junction angles, a. Wood block seated in:one of said channels at. the point of overlapping of said channels and fastening devices extendingfthrough said overlapping portions and into said- Wood block.

4. InA means for framing wall openings, the combination of a plurality of metallic channels associated-'to i'orm a rectangular frame, one ott said channels being provided 'With an extension overlying and co-operating with `an angularlydisposed adjacent channel, a vvoodblock inA one of said channels, fastening meansextending through the overlapping portionsand into said Wood block, and .interlocking means on said eX- tension and adjacent-channel for `forming aVIV holding connection independent of said fastening means.
